Summaries for DCP1B Gene

Entrez Gene Summary for DCP1B Gene

  • This gene encodes a member of a family of proteins that function in removing the 5' cap from mRNAs, which is a step in regulated mRNA decay. This protein localizes to cytoplasmic foci which are the site of mRNA breakdown and turnover. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

GeneCards Summary for DCP1B Gene

DCP1B (Decapping MRNA 1B) is a Protein Coding gene. Among its related pathways are Translational Control and Deadenylation-dependent mRNA decay. Gene Ontology (GO) annotations related to this gene include hydrolase activity and enzyme regulator activity. An important paralog of this gene is DCP1A.

UniProtKB/Swiss-Prot for DCP1B Gene

  • May play a role in the degradation of mRNAs, both in normal mRNA turnover and in nonsense-mediated mRNA decay. May remove the 7-methyl guanine cap structure from mRNA molecules, yielding a 5-phosphorylated mRNA fragment and 7m-GDP (By similarity).
